Discussion
Hexalectris spicata var. spicata occurs in Missouri in calcareous soil in dry forests and limestone glades, often in association with Juniperus in the latter habitat (G. Yatskievych 1999). Detailed descriptions of habitat and associated species for H. spicata var. spicata in Illinois are given by C. J. Sheviak (1974) and for Indiana by M. A. Homoya (1993).
In Oklahoma, populations of Hexalectris spicata var. spicata growing in decaying Juniperus needle litter over sandstone are far more robust.
